I run a business · for firms
The file that runs your firm, rebuilt as an application.
Eleven tabs, one person who understands them, no two people able to edit at once. RunMyB rebuilds it from a description of how the work actually runs: a real application with its own database and its own accounts, run for you, so nobody at your firm owns a server.
A try usually costs an afternoon and a few dollars. A product nobody visits costs nothing, unless it runs AI work on its own, on a schedule.
The RunMyB guide says: Show me the spreadsheet.
How it works for a firm
Describe how the work runs.
The tabs, the exceptions, the rule everyone knows and nobody wrote down — in your own words.
It studies the best, then plans yours.
The platform reads the leading tools of that kind and lays out the plan: what every one has, where yours fits your firm better, what only yours would have. You approve it.
Built, checked, previewed in private.
Your team tries it on a private preview; you accept it, or send it back with a note.
Publish it, then change it as the firm changes.
Say what to change in plain words; the whole build is re-checked, and nothing changes for your users until you release it.
Things firms replace this way
The spreadsheet that has outgrown itself.
A client portal instead of email attachments — clients sign in and see only their own documents.
An internal tracker two people can edit at once.
A point tool bought for one job, rebuilt as exactly the thing you need.
Answers
Can an AI-built app have real user accounts — and can one client see another's data?
Apps built here with accounts get real sign-in: email and password, passkeys and two-factor codes. Every such build must pass an authentication floor whose checks include cross-user isolation, and a build that cannot pass it does not reach you. Between products on the platform the isolation is structural: every hosted product gets its own database and its own sandbox — not a shared table with a customer column.
Can the app connect to our accounting, ERP or practice-management system?
Plan it as a tool of its own. A hosted product runs in a governed sandbox and reaches the outside only through the platform's own controlled doors; it does not sync with those systems. If connecting out is the whole point of your tool, you own the code and can export it to infrastructure you control (Terms §12.1).
What happens to eleven years of records in the old system?
A new product's database starts empty, and we run no migration service. Getting the export out of your old system, and bringing what you need across, is your side of the line — better known now than in week six.
Can we change it ourselves afterwards?
Yes. Describe the change in plain language; the platform makes it, re-checks the whole build against the floor it passed before — it serves, it loads, its data survives a restart, its sign-in still holds — and waits for your approval. Nothing ships until you approve it.
Who looks after it? We have no IT department.
Nobody at your firm has to. Each product runs in its own sandbox with its own database, provisioned and operated by the platform. The same system that built it re-checks it and fixes it, and the code is yours to export to your own GitHub or GitLab (Terms §12.1).
Does this work for a firm in Poland or elsewhere in the EU?
It does, with two limits. The interface is English only, and the platform issues no local invoice, so a firm outside the United States brings its own invoicing and its own accountant.
What stays ours?
Your description of how the firm works and everything built from it are yours (Terms §10, §11), and we will not use what you describe to build a product that competes with yours (Terms §10.1). Clients you bring stay yours: we will not market to them or approach them around you (Terms §10.2).
What we do not do
- We send you nobody you did not bring yourself.
- We do not build phone apps: what gets built runs in a browser.
- We do not move your data: a new product's database starts empty.
- We do not replace your whole software stack: your accounting system stays where it is.

This form needs JavaScript, which your browser has switched off. Write to hello@runmyb.com with the word waitlist and we'll add you by hand.
You're on the list. What we recorded: your address, the consent wording you agreed to, the time, and a one-word note that you came from this page. Nothing else is in that record — no name, no IP address, no tracking.
You won't get a confirmation email. If you want it confirmed, write to hello@runmyb.com and we'll check. If we write, it will be about getting you in — the first thing we ask is what you would build and who it is for, because we let people in one at a time and decide by hand. We can't tell you when, and we won't send anything else in the meantime.
Changed your mind? Write to privacy@runmyb.com and we'll take you off the list.
That didn't go through and it's safe to try again — a repeat submission can't create a duplicate. If it keeps failing, email hello@runmyb.com.
RunMyB is opening in stages, and access is by invitation for now.
